Shoe upper



FIG. 1 is a rear perspective view of a shoe upper showing my new design;

FIG. 2 is a first side view thereof;

FIG. 3 is an opposite side view thereof; and,

FIG. 4 is a rear view thereof.

The even-length broken lines immediately adjacent the shaded area represent a boundary of the design and forms no part thereof. The unshaded regions depicting the circular grommets, the area within the grommet in FIG. 2, and the heel portion of the shoe between the bow ends form no part of the claimed design. The dash-dot-dash style broken line showing of the remainder of the shoe is for environmental purposes only and forms no part of the claimed design. 

CLAIM The ornamental design for a shoe upper, as shown and described.
